For me, the action in turn-based strategy games (specifically Heroes 2 and 3) involves using spells like Portal to Town, Dimension Door, Fly, Walk on Water, View Air, and View Land, among others. These are spells that are almost essential for effective gameplay. The most impactful spell is definitely Dimension Door. With it, you can traverse the entire map, capturing Castles – that's what makes Heroes 3 and 2 such great games. You can truly dominate! (But that's just one of the many positives in these amazing games).
In Heroes 5, you can't really "dominate." Moreover, the game can end abruptly and unexpectedly. For example, an elf might appear with four creatures from your faction, and they become your sworn enemies. This is what really surprises me. Or, what kind of Castle is this Dark Elf Castle, or whatever it's called? It has the strongest creatures, and it's obvious. At least, that was the case before the expansions. I don't know anything about the Dwarf and Orc factions. Maybe something has changed. There's no desire to play such a boring game. In Heroes 4, there was a lot of new content, but most people didn't like it. And in Heroes 5, everything is the same as in Heroes 3, only worse (except for the graphics). Since Heroes 3 is a cult classic, people liked Heroes 5 more than Heroes 4.
